Photorejuvenation is not an unfamiliar term to many people and has long been one of the most popular ways to rejuvenate the skin. However, there are still many people who disagree with photorejuvenation, and they tend to be more concerned with the question: will skin aging accelerate after a period of photorejuvenation? What we usually understand as aging is not really aging in the sense of skin, it is due to the fact that the light that is exposed to our skin over time eventually “ages” the skin, and this effect of sunlight actually begins to accumulate from childhood. We can also notice that Caucasians have more visible wrinkles than we do, probably because their skin is less resistant to light. After the photorejuvenation treatment, the structure of the skin has changed, as shown by the recovery of collagen and especially elastic fibers in the skin. As long as the skin is protected in the future, the aging process will not be accelerated. The United States is the birthplace of photorejuvenation treatment, and the first people to receive treatment were Americans. Two very influential studies have shown that the first people to receive photorejuvenation treatment five years ago were still very satisfied with the results and did not experience accelerated aging.
